  • HYDROMETALLURGICAL REMOVAL of Li.RSENIC from a GOLD-BEARING ARSENICAL FLUE DUST
    HYDROMETALLURGICAL REMOVAL OF li.RSENIC FROM A GOLD-BEARING ARSENICAL FLUE DUST. A. John Monhemius and D. Mensah-Abrampah Department of Metallurgy & Materials Science Royal School of Mines, Imperial College of Science and Technology, London SW7 2BP, U.K. INTRODUCTION An arsenical flue dust, produced during the roasting of sulphidic gold-bearing flotation concentrates at Ashanti, Ghana, contains about 2oz gold per ton (57g/ton) and 30% As as arsenic trioxide, As 203. The recovery of gold from this material is difficult. If it is added into the leaching pachucas for cyanidation with the calcine from the roasters, it causes filtration problems and also leads to high arsenic levels in the plant effluents. Furthermore gold recovery from the dust is not complete during cyanidation due to gold being trapped in undissolved arsenical particles. A method for pretreating the flue dust to remove the arsenic by alkali leaching prior to cyanidation has been investigated. Leaching with sodium hydroxide is used to produce sodium arsenite solution. This may be treated with lime directly to precipitate calcium arsenite or, preferably, first oxidised so that calcium arsenate is precipitated. In this form, the arsenic may be disposed of, since calcium arsenate is a stable compound or alternatively it may be of use as an insecticide. The lime treatment totally regenerates the sodium hydroxide consumed by the dissolution and oxidation reactions and the liquor from precipitation is recycled to leaching. CHEMISTRY OF THE As-H 2 0 SYSTEM The thermodynamic behaviour of the arsenic-water system is illustrated by the potential - pH diagram in Figure 1.

  • Chapter 6.1 Arsenic
    Chapter 6.1 Arsenic General description Arsenic (As) and its compounds are ubiquitous in nature and exhibit both metallic and nonmetallic properties. The trivalent and pentavalent forms are the most common oxidation states. From both the biological and the toxicological points of view, arsenic compounds can be classified into three major groups: inorganic arsenic compounds; organic arsenic compounds; and arsine gas. The most common trivalent inorganic arsenic compounds are arsenic trioxide, sodium arsenite and arsenic trichloride. Pentavalent inorganic compounds include arsenic pentoxide, arsenic acid and arsenates, e.g. lead arsenate and calcium arsenate. Common organic arsenic compounds are arsanilic acid, methylarsonic acid, dimethylarsinic acid (cacodylic acid) and arsenobetaine. Arsenic trioxide is only slightly soluble in water; in sodium hydroxide it forms arsenite and with concentrated hydrochloric acid it forms arsenic trichloride. Sodium arsenite and sodium arsenate are highly soluble in water. Interchanges of valence state may occur in aqueous solutions, depending on the pH and on the presence of other substances which can be reduced or oxidized (1). Sources Arsenic appears in nature primarily in the form of sulfides in association with the sulfides of ores of silver, lead, copper, nickel, antimony, cobalt and iron. Trace amounts of arsenic are found in soils and other environmental media. Arsenic is mainly transported in the environment by water. In oxygenated water, arsenic usually occurs as arsenate, but under reducing conditions, for instance, in deep well-waters, arsenites predominate. In water, the methylation of inorganic arsenic to methyl- and dimethylarsenic acids is associated with biological activity. Some marine organisms have been shown to transform inorganic arsenic into more complex organic compounds, such as arsenobetaine, arsenocholine and arsoniumphospholipids.

  • Hazardous Waste List (California Code of Regulations, Title 22 Section 66261.126)
    Hazardous Waste List (California Code of Regulations, Title 22 Section 66261.126) Appendix X - List of Chemical Names and Common Names for Hazardous Wastes and Hazardous Materials (a) This subdivision sets forth a list of chemicals which create a presumption that a waste is a hazardous waste. If a waste consists of or contains a chemical listed in this subdivision, the waste is presumed to be a hazardous waste Environmental Regulations of CALIFORNIA unless it is determined that the waste is not a hazardous waste pursuant to the procedures set forth in section 66262.11. The hazardous characteristics which serve as a basis for listing the chemicals are indicated in the list as follows: (X) toxic (C) corrosive (I) ignitable (R) reactive * =Extremely Hazardous A chemical denoted with an asterisk is presumed to be an extremely hazardous waste unless it does not exhibit any of the criteria set forth in section 66261.110 and section 66261.113. Trademark chemical names are indicated by all capital letters. 1. Acetaldehyde (X,I) 2. Acetic acid (X,C,I) 3. Acetone, Propanone (I) 4. *Acetone cyanohydrin (X) 5. Acetonitrile (X,I) 6. *2-Acetylaminofluorene, 2-AAF (X) 7. Acetyl benzoyl peroxide (X,I,R) 8. *Acetyl chloride (X,C,R) 9. Acetyl peroxide (X,I,R) 10.
